But as above depends on instructor. The exercises I hate are low resistance fast sprints out of the saddle as not sure they are good for my knees. So just sit down and sprint them instead.

It would be great to have them all networked on a screen. No hiding for those who pretend to up the resistance!!! Really incentive to have resistance, wattage, rpm and HR of everyone up on a big screen. I was thinking that last night during the class.

Spinning has improved my fitness no end but probabley got one of the best instructors in the country Kevin Dawson 10 times BBAR champ and its totally cycling related, been doing his classes 2 years and nearly throw up every class he works you that hard
